Operating Condition
Syntax: SET INSERT ON/OFF
Default: ON
SET INSERT turns insert/overwrite on or off. Set INSERT on to use either the insert or overwrite mode. Pressing the [Insert] key when you have specified INSERT to be on toggles you between insert mode and overwrite mode. In insert mode, the cursor indicator is larger. Press the space bar to insert a space. Set INSERT off to use only the overwrite mode; the cursor indicator is smaller.
